Summing Amplifier using op amp

Summing amplifier using op amp have two or more inputs connected to the inverting terminal and non inverting terminal is grounded (Inverting amplifier configuration). Its output will be negative of the algebraic sum of inputs. Hence the name summing amplifier. It have a negative feedback. Summing amplifier have two variations – summing amplifier with unity …

Linear and Nonlinear Applications of OP-Amp

Op-Amp or operational amplifier have a lot of applications in the modern era of integrated circuits. It can be used in its amplifier mode or switching mode, When the mode of op-amp changes its performance also changes. with this mode change, reference voltage change, feed back change (positive or negative or maybe no feedback) and …

Op-amp comparator circuit

op-amp comparator circuit is an open loop circuit. Because open loop op-amp have very high voltage gain. so small difference in input signals are detected. Here two signals which are to be compared are connected to the two input terminals. output will be either + Vcc or – Vcc. This op-amp camparator circuit is used …

opamp – Introduction to Operational Amplifier

Operational amplifier has two inputs, Inverting (-ve) and non inverting (+ve) inputs and one output. 741 is one of the traditional op-amp, which have 8 pins. two pins are inputs, one pin is output and a Vcc (+ve) and Vee (-ve), which are supply voltages (range 5 to 15 V). It also have two offset …

Thyristor or Silicon Controlled Rectifier (SCR)

Thyristor or Silicon Controlled Rectifier is well known as SCR. This device have four layers, three junctions and three terminals. Three terminals of SCR are gate, anode and cathode. Gate is located close to cathode. Like in PN junction diode, anode and cathode terminal makes thyristor or “silicon controlled rectifier” a RECTIFIER. Gate terminal controls …
